| Answer: Amoebae are often picked up and transported by birds,
e.g. ducks and other animals that move from pond to pond. Amoebae
need only a small volume of water to be transported and so, simply
touching the water may result in some amoebae being transferred.
Some species will live in an animal's gut after contaminated
water has been drunk. These will be passed out of the gut on
defaecation into other water areas where they will establish
new colonies. Some of these forms cause the disease Amoebic dysentery
in humans. |
